Looking for reliable hull cleaning in San Diego? Miami Marine LLC provides underwater hull cleaning, bottom cleaning and running gear service for vessels across San Diego Bay, Shelter Island, Harbor Island, Coronado, and Mission Bay. Our commercial divers come to your marina slip, mooring or private dock, so there is no haul-out and no downtime.

In San Diego's mild, year-round boating waters, marine growth builds quickly. Regular in-water hull cleaning keeps barnacles and slime off your bottom, protects your anti-fouling paint, restores speed and cuts fuel consumption.

• Hull & Bottom Cleaning: Non-abrasive removal of algae, slime and soft growth that is safe for premium anti-fouling paint.
• Barnacle & Hard Growth Removal: Careful scraping of barnacles, tube worms and calcareous growth without scoring gelcoat, barrier coats or transducers.
• Propeller & Running Gear Cleaning: Props, shafts, rudders, trim tabs and thrusters cleared to restore thrust and reduce vibration.
• Intake & Through-Hull Clearing: Sea strainers, raw water intakes and thruster grates cleared to prevent overheating.

In San Diego, most boats and yachts need a hull cleaning every 3 to 4 weeks to stay ahead of slime and barnacles, and more often in the warmest months. We set a recurring schedule around your vessel's use, bottom paint and slip location.

We clean hulls at every marina listed below, plus private docks and residential canals throughout the San Diego area.
